AltOS 1.3.2 — Bug fixes and improved APRS support

AltOS is the core of the software
for all of the Altus Metrum products. It
consists of firmware for our cc1111, STM32L151, LPC11U14 and ATtiny85
based electronics and Java-based ground station software.

This is a minor release of AltOS, including bug fixes for TeleMega,
TeleMetrum v2.0 and AltosUI .

AltOS Firmware — GPS Satellite reporting and APRS improved

Firmware version 1.3.1 has a bug on TeleMega when it has data from
more than 12 GPS satellites. This causes buffer overruns within the
firmware. 1.3.2 limits the number of reported satellites to 12.

APRS now continues to send the last known good GPS position, and
reports GPS lock status and number of sats in view in the APRS comment
field, along with the battery and igniter voltages.

AltosUI — TeleMega GPS Satellite, GPS max height and Fire Igniters

AltosUI was crashing when TeleMega reported that it had data from more
than 12 satellites. While the TeleMega firmware has been fixed to
never do that, AltosUI also has a fix in case you fly a TeleMega board
without updated firmware.

GPS max height is now displayed in the flight statistics. As the
u-Blox GPS chips now provide accurate altitude information, we've
added the maximum height as computed by GPS here.

Fire Igniters now uses the letters A through D to label the extra
TeleMega pyro channels instead of the numbers 0-3.
